Bent pipe machining device of small-diameter thin-walled pipe for spraying and atomizing in deodorization equipment

Abstract

The invention discloses a bent pipe machining device of a small-diameter thin-walled pipe for spraying and atomizing in deodorization equipment, the bent pipe machining device comprises a positioning bracket, a fastening assembly, a first positioning shaft, a fixed and movable pulley fixing rotating arm, a fixed pulley and a movable pulley, and the peripheries of the fixed pulley and the movable pulley are respectively provided with a circular arc groove matched with the outer wall of a to-be-bent pipe fitting. One end of the to-be-bent pipe fitting penetrates through a pipe bending hole and is fastened to the fastening assembly, the to-be-bent position of the to-be-bent pipe fitting is located at the pipe bending hole, and a supporting ball at the front end of a movable screw rod is always located at the stressed position of the pipe bending hole by adjusting a tightening nut. The bent pipe machining device of the small-diameter thin-walled pipe for spraying and atomizing in the deodorization equipment can ensure that the bent pipe part is not flat, wrinkled or broken, the appearance is smooth, and the bent pipe machining device is very suitable for trial production of products and small-batch production, simple in manual operation, low in investment and quick in effect taking.

Description

technical field [0001] The invention relates to deodorizing equipment, in particular to a pipe bending device for spraying and atomizing small-diameter thin-walled pipes in the deodorizing equipment. Background technique [0002] In the deodorization equipment, it is necessary to use more small-diameter thin-walled pipes for spraying and atomization. These small-diameter thin-walled pipes are laid according to the requirements of the internal structure in the deodorization equipment, and sometimes even need The small-diameter thin-walled tube needs to be bent to fit the internal structure of the deodorizing equipment. [0003] There is an insurmountable technical problem in the bending of small-diameter thin-walled tubes: either the tube wall at the bend will be wrinkled due to the extrusion during bending, or the circular inner hole at the bend will be wrinkled due to bending. The extrusion of the tube is flattened, which greatly increases the fluid resistance in the tube,...

Problems solved by technology

[0003] There is an insurmountable technical problem in the bending of small-diameter thin-walled tubes: either the tube wall at the bend will be wrinkled due to the extrusion during bending, or the circular inner hole at the bend will be wrinkled due to bending. Squeezed and flattened, which greatly increases the fluid resistance in the tube, the smaller the bending angle, the more serious the problem

Since the pipe fittings to be bent are filled with fine sand, the wrinkling and flattening of the pipe wall at the bend will be much better, but the bend will still be flattened, wrinkled, and even cracked, and the quality is difficult to control
